TrackerScope™ (in Beta), based on BayCloud's cloud hosted ScanAPI™, shows all the resources when a browser visits any particular web page. This is done from a cloud based client so does not need a download or need to collect anyone's PII. Trackers are defined as those resources that store persistent high-entropy cookies with more than a few hours duration, third-parties which send unrequested XHRs and other techniques whose purpose is probably tracking. By default it sends requests with the DNT header set, though you can tell it not to.

Because the scan is executed on a cloud based client it is certain that no previous consent has been given so any storage of a persistent high-entropy cookie gives an indication of how a site complies with the EU privacy directive as well as Do Not Track.

Each circle represents a resource accessed when rendering the page, i.e. even if links on the page are not activated. Click on any circle to show a panel detailing the response headers, cookies placed, latency and DNT response. The panel can be dragged around the screen for a better view. If the results from a page are a bit confusing you can restrict it to resources with trackers only by clicking the "show trackers only" checkbox above.
